TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOHN W. PIIILLIPPI, of Stahlstown, in the county of Westmoreland, and State of Pennsylvania, have invented a new and useful Improvement in Wagon-Brakes; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had i to the accompanying drawings, making a part of this specification, in which-- Figure 1 is a plan view of the rear portion of the wagon.

Figure 2, an'end View. p

Figure 3, a longitudinal section as indiea-ted'by the line at in the two previous figures.

Figure 4, a view in detail of arrangement for rendering the brakes inoperative when backing wagon.

Figure 5, a view in detail of grooved friction-roller, shown in figs. 2 and 3, between rear axle and bolster.

Like letters in the different figures of the drawings indicate like parts. I

My invention consists of the following improvements in the construction of wagon-brakes: first, constructing a wagon so that the hind wheels will approximate the fore Wheels by means of an elongated. slot in the coupling-pole and friction-roller under the rear bolster, and thus operate the brakes automatically; second, the arrangement of a check or stop on the front axle, in combination with the coupling-pole for nullifying the action of the brakes when backing the wagon.

To enable any one skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A represents the holster; B, the friction-roller provided with four grooves a a a a, (see fig. 5;) C, the rear axle; bands 6 I) are attached to the sides of the axle over the outergrooves of the roller, (see fig. 2,) and two more, b b, to the sides of the bolster under the inner grooves of the roller. A plate, D, is attached to the couplingpole, (see figs. 1; and The brake-lever is placed thereon, and isregulated in its sliding movement by the guides a c. On the ends of the lever are the brakes 01 (Z. F F are rods conn ccting the lever with the bolster by means of the two vertical rods 0 0, (see figs. 2 and These rods e e are so constructed as to have loops or links formed in the centres of. them, to which the rods F F connect by their hooked ends. The rods e e are retained sufiiciently loose in hooks attached to the holster and axle as not to interfere with a'proper movement of the axle and bolster relatively to the roller. fis the'elongat-ed slot in the pole through which-passes the kingbolt for coupling the pole to the front axle. G is the check or stop properly attached to the front axle, (see fig. 4,) so that it can be moved around and made to impinge against the front end of the coupling-pole, and when in this position it may be retained by a suitably constructed spring attached to the axle or sand-board, and likewise when in its original position, to prevent any possibility of its working around to the end of the. pole and thus interfere with the action of the brakes when desired.

Operation.

The moment the horses begin to hold back on the tongue, when the wagon is descending a hill, the revolu= tion of the hind wheels is instantly stopped by the automatic action of the brakes in this wise: The hind wheels are allowed to approximate the fore wheels by means of the elongated slot and friction-roller, which movement of the hind wheels operates upon the rods attached to the brake-lever, drawing the brakes back upon the wheels The strain or pressure on the rods of the brake-lever is exerted outwardly from their ends, and they are therefore not liable to bend or break. The securing of the bolster to the roller, and the roller to the axle by bands in the grooves of the so me, serves to give a steady movement to the bolsters relatively to that of the axle, and hence will prevent any liability of the brakes to fail in their operation against the wheels. The brakes will operate as eifeotuslly with a load of rails or timber on the bolster as with the body on the same. Topreve'nt'the hind wheels approximating the fore wheels in backing the wagon, and thus affect thebrakes the sameas descending a hill, the check or stop is caused to impinge on to the front end of the coupling-pole in the manner as herein described. I

Having thus fully described my invention, what I claim therein as new, and desire to secure by Letters Patent, is-

1. The bolster A, arranged and combined with the grooved friction-roller B and axle C by means OflMLlldS b b b b, substantially inthe manner as herein described. I

2. The rods F F and rods 1: e, as tirranged for combining the brakes with the bolster and axle, substantially in the manner as herein set forth. 3. The construction of an elongated slotfin the couplingqiole, in combination with the bolster and frictionroller, substantially in the manner as described.

4. The check or stop as arranged and combined with the coupling-pole, substantially in the manner and r for the purpose as herein set forth.
